STOP AND WASTE COCK.

SPECIFICATION forming part of Letters Patent No. 664,354, dated December 1s, 1900.

nppneeeon ined october 1,1900. serial No. 31,601. (No model.)

To @ZZ whom t may concern.:

Be it known that I, JOHN H. JOHNSON, a citizen of the United States of America, residing at Chicago, in the county of Cook, in the 5 State of Illinois, have invented a certain new and useful Improvement in Stop and'Waste Cocks, of which the following is a description, reference being had to the accompanying drawings, forming a part ofrthis specification.

My invention has for its object a simple improvement in stop and Waste cocks of familiar construction whereby the accurate assembling of the parts, both originally and in changing from a right-hand to a left-hand cook, is facilitated and whereby the valveseat is more efficiently protected from dirt.

In the accompanying drawings, Figurel represents a front elevation of the improved cock with its parts assembled as a right-hand zo cock; Fig. 2, a corresponding view with the parts assembled as a left-hand cock; Figs. 3 and 4, views corresponding, respectively, to Figs. l and 2, with the cap and handle oi' the cock removed; Fig. 5, an elevation of the z5 right side ofV the parts as shown in Fig. 1,

with the handle removed and the cap in section, the valve being open; and Fig. 6, a crosssection through the waste holes with the parts in the same position; Fig. 7, a view cor- 3o responding to Fig. 5 with the valve closed, and Fig. 8 a View corresponding to Fig. 6 with the valve closed; Fig. 9, a View corresponding to Fig. 5, but looking at the lefthand side of the parts as shown in Fig. 2, the 3 5 valve being open, and Fig. l0 a corresponding view with the Valve closed, and Fig. ll an inside view of the cap.

The same letters of reference are used to indicate corresponding parts in the several 4o views.

A is the body or casing of the valve, provided with the upper and lower pipe connections B B and with the usual waste-hole Cin its side.

D is the tapering plug or Valve proper, seated in the transverse tapering bore in the valvebody and confined by a nut and washer at one end, as usual. It is provided with the usual transverse passage E in line with the 5o pipe connections B B and with the waste-hole F, communicating therewith, Figs. 6 and 8.

At its side adjacent the operating-handle the valve-body is provided with a circular iiange G,Figs. 3 and 4, over which is adapted to snugly fit the inner edge of the rim of the cap H. Projecting from this flange G is a stop lug or projection I, adapted to coperate with lugs J J", formed upon the interior of the cap H, the space between these lugs J J, into which the stop-lug I projects, being just sufficient to permit a quarter-turn of the cap from the point at which one of the lugs of the cap contacts with the stop to the point at which the other lug comes into contact with it and arrests the movement of the cap.

The cap H is provided upon its interior with a third lug K, located midway between the lugs J J', but of only about one-half the depth or length of those lugs, so that in the turning of the cap the lug K clears the stoplug I, projecting from the iange" G. The purpose` of this lug` K is to form between itself and the lugs J J two` opposite seats or recesses L L for the reception of a lug M, projecting radially from the side of the valve D. The projecting portion of the valve D beyond the lug MA is circular in cross-section and accurately ground or turned to form a snug fit in the circular opening in the cap H, and thereby prevent entrance of dirt between the two, while the snug lit of the opposite end of the cap lupon the flange G of the valvebody prevents entrance of dirt at that point.

The valve D is provided with a central square recess or socket N to receive the correspondingly-shaped end of the operatinghandle O, which latter is secured in positionl by the usual set-screw P.

In assembling the parts after the valve D has been inserted in the body and secured by the nut and washer upon its smaller end it is turned until the lug M, projecting from its side, is brought into line with the lug I, as shown in Figs. 3 and el. In this position of the parts the valve is openw and adapted for 95' operation as either a righthand or a left-hand valve, being secured in the position shown in Fig. 3 for a right-hand valve and in the position shown in Fig. et for a left-hand valve. To properly set the tapering plug or valve for use as either a right-hand or a left-hand vai-ve, therefore, it is simply necessary to turn it IOO until the flugs -I-and M are brought into line. The next -step is to apply the cap H in such position that its interior lugs J J, coperating with the stop-lug I, will permit the cap/tov be turned forward to close the valve, it being understood that 4valves of ithischaracter are usually in open position when the'operatinghandle is turned upward into vertical 'line' with the piping, as in Figs. 1 and 2, and are closed by pulling the handle downward andv forward to horizontal position. In applying the cap H the lug M, projecting from the valveplug, "willenter the recess L or L'lbetween the lug K and theI lugs J J', fitting in the recessV L', as in Fig. 5, if the Valve is to be used as a right-hand valve, and in the recess L, as in 'Fig-9, if the valveis to be used as aleft-hand valve, and 'thereby looks the cap 'H Ato'the valve'D, sothattheyturn together. After the cap has been thus properly applied the 'squaredend-of-the handle /is inserted in the socket `in the end of the valve and vsecured in place by the set-screw P, the latter valso `servingto hold the cap H `in place.

iIf theiparts have been assembled for useas aright-hand valve, as in Figs. l, 3, 5,'and 7,

when the valve is in open position the lugM upon 'the valve-plug will be seated in the re-g cess Lbetween the lugs K and J in thecap Hand Athe extreme inner end of the lug J',

"willbe in'contact with or immediately adjacent the rear side of the stop-lug Iupon theiv valvebody,(hid by the lug M in Fig. 5.) Whenl the operating-handle is then swung forwardl and downward, the partswill beiturned in the direction ofthe arrow until the'lug Jcomes infcontact with the'forward side of the stop-i `lugI, as in Fig. 7, 'which will'serve to arrest the parts. This quarter-turn of the valve in `thebody'will have carried'itfronn the position; shown in Fig. 6 to that'shown in Fig. 8, cuttingi off "communication 'with the lower'pipe andi permitting the `upperpipe :tovdrain throughl the waste-holes F and'C and the transversel opening 'E throughthevalve, as usual. g

If -the partslhave been assembled for use as; aleft-hand valve, as in Figs.'2, 9, and ,10, the@y `lug'M upon 'the valve-'plug will be seated in lug I, (hid by the lug M inFig. 9,) and vupon 'giving the `parts a quarter-turnto close the valve and drain the upper pipethe lug will be'broughtinto contact'with'the forward side 4'of thestop-lug I and arrest the parts at the 'end of'su'ch movement, asin Fig. lO.

As Vbefore explained, the valveplug is turned to bring the lug M intolinewith the stop-lug I, EFigs. 3 and 4, beforethe cap His applied, the'bringing of the parts to this'positionservi'ng 'to set the valve-plug properly which the lugs I and M project. that the cap H canbe applied only-when the -Vthe lugs J J at'the opposite side of the cap from the open space between said lugs into It follows lugs M and I are in such relation to each Y other that bothcan enter at once between the lugs J and J', which they cannot do if the latter are more than-a quarteriturnapart.

yIt `follows from `rthe lforegoingvdescription that ifithefvalve-plug is turned soas'to bring the :lugs M and I into 4line before applying the'c'ap H orso as to bring Ethem within a quarter-'turn of each other vit isinot possible toapply the cap'in such a-waythat the'valve Willnot bef'operative either -as'a right-'hand valve or Aas Ya left-hand vvalve, (one or the other,) while to insure its Voperating as the one desired it its simply `necessary toapply the cap so that it may be turned in the proper direction.

Tarn of course-'awarethat valves offthis general character employingfaicap iitting over the valveplug-anda flange upon thevalvebody and 'turning 'with .the valve-plug "and provided upon A"its interior with lugs-coperating with a stop similar tothe stop-lug 'I upon the valve-body are oldandfwell'known,

'as shown, forinstance, in the-Muell'erpatent,

No. 513,272,and1ny-present invention there- 'fore consists simply'in an improvementupon such prior valves. Inthe val'vefshown inthe Muellerpatent,1for instance, the cap can be applied regardless ofthe-position ofthe valve- In -respect'to facili-tyifor assemblage of theiparts,

Vtherc'ore,=my valve is an improvementupon Vthis one for the yreasons which lhave been pointed out.

Again, in the practic'almanufacture of the Mueller valve it has'beenlfound `necessary'to i provide a 1 projecting boss i upon -one 'corner of the nsquare 4,outer end fof the valve-plug for the reception of the threaded lhole into=which the set-screw is screwed in order `to afford a sufficient bearing for "said lsicrew,"withthe `result that it haslbeen necessary to providethe cap with recesseslat two Vof itsadjacent corners to permitthepassage ofthe cap over this projectingfbossin'assembling the parts,and-when thecap isapplied to the valve one orlthe other' of saidfrecesses not fitting over thelboss necessarilyile'aves-an opening for'- the free f passage of f dirt finto the yinterior ofthe cap,thus defe'ating'one of the IOO IIO

objects for which the cap is employed. In-

.I claim- 1. In a stop and waste cock such as described, the combination of ytbemvalve-body having the flange G and stop-lug I, the plugvalve D provided with the lug M, and the cap H fitting over the end of the valve D and around the Iiange G and provided upon its interior with the lugs J J and K, the lugs J J cooperating with the stop-lug I to arrest the turning movement of the cap and valve, and thelug K forming between itself andthe lugs J J two recesses L L for the reception of the lug M upon the valve D, substantially as and for the purpose specified.

2. In a stop and waste cock of the character described, the combination of the Valvebody having the flange G and stop-lug I, the plug-valve D provided with the projecting lug M, and the cap H fitting over the projecting end of the valve D and surrounding the iange G, and provided upon its interior with the lugs J J connected by the rib Q, andthe lug K intermediate the lugs J J', the lugs J J coperating with the stop-lug I to arrest the turning movement of the cap and valve and the rib Q serving to prevent the application of the cap except when the valve D is in proper position, and the lug K serving to form between itself and the lugs J J two recesses L L for the reception of the lug M upon the valve D, substantially as and for the purpose specified.
